CONNECTING VESR9XX SERIAL SERVERS TO SERIAL DEVICES

VESR9xx Serial Servers can be configured to connect to serial devices using RS-232, RS-422, RS-485 2-wire and RS-485 4-wire.

RS-232 connections support eight signal lines plus Signal Ground. Signals are single ended and referenced to Ground. Default communications parameters are 9600, 8, N, 1 and no flow control implemented.

RS-422 connections support two signal pairs: TDA (-), TDB (+), RDA (-), RDB (+) and GND. The data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference.

RS-485 connections support 2-wire or 4-wire operation.

When configured for 4-wire operation the connection supports two signal pairs: TDA (-), TDB (+), RDA (-), RDB (+) and GND. This makes full-duplex operation possible. The data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference.

When configured for 2-wire operation the connection supports one signal pair: Data A (-) and Data B (+) signal channels using half-duplex operation. The data lines are differential with the Data B line positive relative to Data A in the idle (mark) state. Ground provides a common mode reference.

CONNECTING THE VESR901-X

The VESR901-x has one serial connection that supports RS-232, RS-422 and RS-485 (2- and 4-wire). The unit has two connectors: a DB-9M connector and a 5-position terminal block.

If you select RS-232 mode when you configure the serial server, you must connect the serial device to the serial server via a serial cable. The VESR901 is a DTE. If the serial device is a DTE, use a null modem (cross-over) cable. If the serial device is a DCE, use a straight-through cable.

If you select RS-422 mode, RS-485 2-wire mode, or RS-485 4-wire mode when you configure the serial server, you must connect the serial device appropriately, via the 5-position terminal block.

Note: Refer to Appendix D for connector pinout information.

Note: Factor default parameters are listed in Appendix A

DESCRIPTION OF SERIAL SERVER PROPERTIES

The following serial server properties are ordered alphabetically to assist you in finding the information you need.

BAUD RATE

Baud Rate is the communication speed of the link between the serial server and the device attached to its serial port. Both these devices must be configured to operate at the same baud rate. Baud rate values range from 75 to 230,400 Baud. (Refer to Appendix B for specific baud rates that are supported.)

CHARACTER COUNT

Character Count controls the maximum number of characters to buffer before sending the characters to the network. Larger values decrease the number of network packets, but increase the amount of time to receive characters. Smaller values increase the number of network packets, but decrease the amount of time to receive characters. The range is 1 through 65535.

CONFIGURATION FILES

Configuration files contain all configuration settings for the serial server. When the serial server settings have been configured you can save the settings using Vlinx Manager. Existing configuration files can be Opened (from Vlinx Manager), which loads them into the serial server. This allows the same configuration to be applied to multiple serial servers, or to reload a previously used configuration.

DATA/PARITY/STOP

The number of Data bits, type of Parity and number of Stop bits selected define the serial port parameters at which the serial server will operate. These parameters must be configured to match the parameters set on the serial device connected to the serial server's serial port.

Data Bits controls the number of bits of data in each character. Options include 5, 6, 7 or 8 data bits.

Parity controls the error checking mode. Options are No Parity, Odd, Even, Mark or Space.

Stop Bits controls the number of bits to indicate the end of a character. Options include 1, 1.5 and 2. (1.5 bits is only valid when 5 data bits is selected, which is rare. The 2 stop bits setting is only valid when 6, 7 or 8 data bits is selected.)

DEFAULT GATEWAY

The Default Gateway address sets the default route to remote networks, enabling users to access the serial server from outside the local network.

DELIMITER 1, DELIMITER 2 AND DELIMITER REMOVAL

Delimiters and Delimiter Removal enable you to control how characters received on a serial port are sent across the network. Delimiters are ASCII characters specified by the user when configuring the serial server. The serial server takes action when it recognizes the specified character(s) on its serial port.

DELIMITER 1

Delimiter 1 is a start delimiter. The range of ASCII values is 0 through 255.

DELIMITER 2

Delimiter 2 is an end delimiter. The range of ASCII values is 0 through 255.

DELIMITER REMOVAL

Delimiter Removal controls removing of Delimiter 1 and Delimiter 2 from the received characters before the received characters are sent to the network.

HOW DELIMITERS WORK

When only Delimiter 2 (the end delimiter) is enabled, characters received by the serial port are accumulated in a buffer. When the end delimiter is received on the serial port, the buffered characters, including the end delimiter, are sent to the network. All characters received after the end delimiter are again buffered until another end delimiter is received.

When both Delimiter 1 (start delimiter) and Delimiter 2 (end delimiter) are enabled, characters received by the serial port will be discarded until the start delimiter character is detected on the serial port. The serial server then buffers the start delimiter character and all subsequent characters received after it until the end delimiter is detected. When the end delimiter is received, the buffered characters, including the start and end delimiters, are sent to the network.

When Delimiter Removal is enabled it removes the delimiter character(s) before sending the other characters across the network.

DHCP

DHCP (Dynamic Host Configuration Protocol) is a protocol used on special servers that supply IP addresses to network nodes on request.

When DHCP is enabled on the serial server, on power up it sends a DHCP request to the DHCP server, which assigns a dynamic IP address, subnet mask, and default gateway to the serial server.

When DHCP is disabled (static IP addressing), the IP Address, Subnet Mask and Default Gateway fields must be set manually by entering the appropriate addresses in these fields. If you do not know what addresses to use in these fields, ask your network administrator.

Notes: This product is factory defaulted to the DHCP mode. It is intended that your network's DHCP Server provide the IP address assignment. If there is not a DHCP server on your network, the device will default to IP address 169.254.102.39.

A dynamic address assigned by the DHCP server may change if the server loses the Ethernet connection or power is removed. If a device on the network that normally communicates with the serial server is configured to communicate with a specific IP address of the serial server, and the IP address has been changed, the device will not be able to communicate with the serial server.

FIRMWARE VERSION

The Firmware Version number (Vx.x.x) indicates the serial server's currently loaded firmware release. From time to time new firmware is made available and can be uploaded into the serial server using Vlinx Manager.

FLOW CONTROL

Flow Control determines the type of handshaking that is used to control sending and receiving of messages. Options include No Flow Control, Hardware Flow Control (RTS/CTS) and Software Flow Control (XON/XOFF). The Flow Control setting must match the requirements of the serial device connected.

Note: Select No Flow Control when setting the port as RS-422 or RS-485 4-wire.

FORCED TRANSMIT

Forced Transmit controls the maximum amount of time that characters can be buffered before sending the characters to the network. Larger values decrease the number of network packets, but increase the amount of time to receive characters. Smaller values increase the number of network packets, but decrease the amount of time to receive characters. The range is 1 through 65535.

HARDWARE VERSION

The Hardware Version number of the serial server hardware is displayed on the Login page of Vlinx Manager.

INTER-CHARACTER TIMEOUT

Inter-character Timeout controls the maximum duration between received characters before sending the characters to the network. Larger values may decrease

the number of network packets, but increase the amount of time to receive characters. Smaller values may increase the number of network packets, but decrease the amount of time to receive characters. The range is 1 through 65535.

IP ADDRESS

Software or hardware attempting to access the serial server via the network must know the IP Address of the server. In DHCP mode (factory default), the serial server requests and receives a dynamic IP address from a DHCP server when it first connects to the network. If there is not a DHCP Server on your network, this device will automatically default to IP Address 169.254.102.39. If the serial server is unable to connect to your network using this address, there are two methods to manually configure the IP Address.

1. Method One: Change your PC Network to Match the Serial Server a. Open the network connection on your PC

Wire Properties General | Authentication | Advanced | Connect using 3Com 3C920 Integrated Fast Ethernet Configure... This connection uses the following items: QoS Packet Scheduler Network Monitor Driver Internet Protocol (TCP/IP) Install Properties Description Transmission ControlProtocol/Internet Protocol. The default wide area network protocol that provides communication across diverse interconnected networks. Thing like to notification areas when connected Notify go when this connection has linked or no connectivity OK Cancel

b. Click on Internet Protocol (TCP/IP) and click . Change the parameters to the following:

IP Address = 169.254.102.1

Subnet Mask = 255.255.255.0

Default Gateway = 169.254.102.100

Internet Protocol (TCP/IP) Properties General You can get IP settings assigned automatically if you network supports this capability. Otherwise, you need to ask our network administrator to the appropriate IP settings. □ Listen an IP address automatically □ Use the following IP address: IP address: 103 254 102 1 Cybernet mask: 265 295 0 0 Default gateway: 103 254 102 10C □ Logitting DNS server addresses □ Log the following DNS server addresses: Enlarged DNS server: Enlarged DNS server: Advanced... OK Cancel

c. Use the Vlinx™ Manager Software to search for, discover, and configure the unit.

1. Method Two: Change the serial server's network setting to match your PC using Console Mode

a. Connect a null modem serial cable (crossover cable) from Port 1 on the serial server to an available COM port on your PC.

b. Open Hyper Terminal or similar serial emulation software and connect to the COM port used in the step above. Ensure the port is configured to 115,200 baud, 8 data bits, and 1 stop bit.

c. Enter Console Mode. Press and hold the serial server's RESET SWITCH for 2 to 10 seconds. The LED indicators will respond as follows:

MODEL	PORT 1 LED	PORT 2 LED	READY LED
1 Port	OFF	N/A	ON
2 Port	OFF	ON	OFF

d. Release the RESET button. The READY LED will blink once per second for 5 seconds. This indicates that the serial server is re-booting in Console Mode.

e. When the serial server has successfully restarted in Console Mode, the READY LED will be OFF and the PORT 1 LED will be on.

f. Open the Vlinx™ Manager Software and select "Serial Port" as the method to connect to the device.

g. After logging in, click on .

h. Un-check the box next to "I want DHCP to setup the Network."
i. Re-configure the serial server's Network Settings to something within the range of your PC's Network Setting. For example
If your PC is configured to:
IP Address = 192.168.0.1
Network Mask = 255.255.255.0
Default Gateway = 192.168.0.100
Configure the serial server to:
IP Address = 192.168.0.50
Network Mask = 255.255.255.0
Default Gateway = 192.168.0.100
j. Save the settings and remove power from the serial server.
k. Apply power to the serial server. Open the Vlinx™ Manager Software and select “Network” as the method to connect to the serial server
1.

LINK STATUS

Link Status of the currently selected serial server is shown on the Login page of Vlinx Manager. Link status indicates the type of Ethernet connection between the computer and serial server. It will either display 10BaseT or 100BaseTX in full duplex or half duplex. Link status is dependent on the LAN, switches, hubs used in the LAN topology.

MAC ADDRESS

The MAC Address is a hardware level address of the serial server that cannot be changed. It is assigned in the factory. Every Ethernet device manufactured has its own unique MAC address. The MAC address of each serial server is printed on the device's label. The MAC address of the currently selected serial server is also displayed on the Login page of Vlinx Manager.

MODEL

The Model number of the currently selected serial server is displayed on the Login page of Vlinx Manager.

NETWORK PROTOCOLS

Network Protocols available for use on VESR9xx serial servers include TCP, UDP, VCOM and Paired Mode.

NETWORK WATCHDOG

Network Watchdog controls the duration of network inactivity when a network connection is determined idle and causes the connection to be forced closed. The range is 1 through 65535 milliseconds.

PAIRED MODE

Paired Mode enables two serial servers to operate across the network like a "wire replacement" between two serial devices. (Paired Mode is also called SERIAL TUNNELING.) Serial devices connected to serial servers on each end of the link can communicate as it they were connected by a serial cable.

For Paired Mode to work one serial server must be configured as a TCP server and the other as a TCP client.

The serial server configured as the TCP client initiates connections. You must set up the IP address and port number of the server that you want the client (serial server) to communicate with. You also select whether you want the serial server to connect at power up or only when it receives data from the device connected to its serial port.

The serial server configured as a TCP server waits for connections to be initiated by another network device. You must set up the TCP port number on which it will listen

for connections and set the maximum (up to four) number of simultaneous connections it will accept. You can filter the connections it will accept based on specific IP addresses or ranges of IP addresses that you specify.

PASSWORD

When you first receive the VESR9xx serial server from the factory the Password is blank so that you can initially access the serial server without entering a value into this field. To ensure security you should create and save a password the first time you configure the serial server. After a password has been set up it must be entered each time you login to Vlinx Manager. The password is used to access the configuration pages from the Vlinx Manager Login page and can be changed from the General page.

SERIAL INTERFACE MODES

Four serial interface modes of operation are:

RS-232 - Point-to-point serial communications connection used by PC COM ports and many other systems. Capable of baud rates up to 115.2 kbaud over short distances (typically 50 feet). Typically uses DB-9 connectors but terminals are also used on VESR9xx serial servers.

RS-422 - Point-to-point communications using a transmit pair and a receive pair. RS-422 can operate at higher speeds and longer distances than RS-232. Typically uses two shielded twisted pairs and screw terminals but DB-9 connectors are also used on VESR9xx serial servers.

RS-485 2-wire - Similar speed and distance specifications as RS-422 but allows multidrop connections. Typically uses one shielded twisted pair and screw terminals but DB-9 connectors are also used on VESR9xx serial servers.

RS-485 4-wire - Similar speed and distance specifications as RS-422 but allows full-duplex connections. Typically uses two shielded twisted pairs and screw terminals but DB-9 connectors are also used on VESR9xx serial servers..

Select the appropriate serial interface mode for the type of connection between the serial server's serial port and the device connected to it.

Note: Refer to the Appendix D for connector and pin-out details.

SERIAL SERVER NAME

Serial Server Name is a unique name assigned to the serial server. It must be a valid hostname as defined by RFC-952 and RFC-1123. The rules are:

It must consist only of the characters "A" to "Z", "a" to "z", "0" to "9" or "-"

It can start or end with a letter or a number, but it must not start or end with a "-". It must not consist of all numeric values.

SERVER SERIAL PORT NUMBER

The Server Serial Port Number of the currently selected port is shown in this field. VESR901-x serial servers feature one serial port.

VESR902D-x and VESR902T-x serial servers feature two serial ports.

SERIAL WATCHDOG

Serial Watchdog controls the duration of serial inactivity when the serial port is determined idle and causes all connections for that serial port to be forced closed. The range is 1 through 65535 milliseconds.

SUBNET MASK

The Subnet Mask specifies the network mask the serial server uses when on a subnetted network.

For a Class A network (IP addresses 0.0.0.0 through 127.255.255.255) the default subnet mask is 255.0.0.0.

For a Class B network (IP addresses 128.0.0.0 through 191.255.255.255) the default subnet mask is 255.255.0.0

For a Class C network (IP addresses 192.0.0.0 through 233.255.255.255) the default subnet mask is 255.255.255.0

For a Class D network (IP addresses 224.0.0.0 through 239.255.255.255) and Class E Networks (IP addresses 240.0.0.0 through 255.255.255.255) the subnet mask is ignored.

VESR9xxserial servers come from the factory with a default subnet mask value of: 255.255.255.0

TCP (TRANSMISSION CONTROL PROTOCOL)

TCP (Transmission Control Protocol) provides reliable connection-oriented network communication with error checking. In TCP mode the serial server can be configured as a client or a server.

When the serial server is configured as a TCP client it initiates connections with a server on the network. You must set up the IP address and port number of the server that you want the client (serial server) to communicate with. You also select whether the serial server is to connect at power up or only when it receives data from the device connected to its serial port.

When the serial server is configured as a TCP server it waits for connections to be initiated by another network device. You must set up the TCP port number that it will listen to for connections and set the maximum (up to four) number of simultaneous connections it will accept. You can filter the connections it will accept based on specific IP addresses or ranges of IP addresses that you specify.

UDP (USER DATAGRAM PROTOCOL)

UDP (User Datagram Protocol) enables applications using UDP socket programs to communicate with the serial ports on the serial server. UDP protocol provides connectionless communications, which allows data to be broadcast to and received from multiple nodes on a network. (Because it is a connectionless protocol UDP does not guarantee the delivery of a datagram and the datagram is only be sent once.)

In UDP mode, if you want to control what network node receives data, you must specify the IP address and UDP port the data will be sent to. You can choose to send to:

Nobody

All nodes at a specific UDP port number. (This is called broadcast.)

Specific IP addresses and UDP port numbers. (This is called unicast.)

A range of IP addresses and UDP port numbers. (This is called unicast range.)

You can also configure the serial server to receive from nodes on the network using the same list of configuration options.

VCOM (VIRTUAL COM PORT)

When the Network Protocol is set to VCOM (Virtual COM Port) the serial server communicates over the network with a PC, acting as a remote COM port for the computer.

Both the serial server and the computer must be configured for VCOM operation. Virtual COM ports can be set up on the PC using the Vlinx Manager software.

In the RS-422 mode, TX lines are outputs and RX lines are inputs. Connect the serial server TXB(+) line to the RXB(+) line of the serial device, and the serial server TXA(-) to the RXA(-) of the serial device.

Ground is signal ground and provides a common mode reference for the RS-422 Receiver and Transmitters.
